A tiny “rainbow on a chip” could help supercharge 6G networks

Researchers have created a tiny chip that produces a stable “rainbow” of light capable of generating multiple high-frequency signals at once, potentially boosting the speed and capacity of future 6G networks. Its extreme precision could also make it valuable for quantum timing, navigation, radar, and even space-based technologies [1].
